Attempt to take over all *SAN builds.
MSAN has a lot of coordination required between gn/BUILD.gn and gn_flavor.py.
I'd like to follow up to move more of this into gn/BUILD.gn, to make it easier
to use locally.
The compile steps should be much faster now. We no longer build CMake
and Clang for every run, instead using the clang_linux CIPD package. This
removes the need for all the third_party/externals/llvm/... dependencies.
Similarly, since we're using the clang_linux package, we no longer depend
on Chrome's Clang, and thus no longer need to sync chromium on these bots.
Instead of packaging up MSAN libraries and llvm-symbolizer in the compile
output, I have the test / perf bots also depend on the clang_linux package.
These do not vary from build to build.
No more need for the xsan.blacklist -include hack: Clang, GN, and Ninja
all track changes to xsan.blacklist without our help.
This has the incidental effect of upgrading the compiler used by *SAN
bots from Clang 3.8 to Clang 3.9.

I just burned 2 days debugging a confusing interaction between ccache
and the -fsanitize-blacklist argument to Clang. Let's see if we can
live without ccache (swarming affinity + Ninja seems pretty decent).
As a point of reference, the Mac bots have been looking for ccache but
failing to find it. They're proof this will be fine.

This ought to support compiles for now.
Am I picking up my CIPD ndk packages right?
The main thing to note is that I'm passing the target_arch directly through
as target_cpu. This means these bots will have a slightly different naming
convention than we've been using, but it'll agree with what you must type
yourself when using GN to build for Android:
- Arm7 -> arm
- Arm64 -> arm64
- Mips -> mipsel
- Mips64 -> mips64el
- x86 -> x86 (unchanged)
- x86_64 -> x64

Also:
* Pass through a new property 'patch_storage' to DM/Nanobench/Coverage. This will be used by the different frameworks to figure out if it is Rietveld or Gerrit issue.
* Calculate issue and patchset for Gerrit patches similar to Rietveld.

Break Skia recipe module into:
- skia_vars: defines and stores variables (eg. paths)
- skia_step: utilities for running Skia steps
- skia_flavor: flavor-specific stuff
- skia: top-level setup, checkout, test/perf steps, etc etc
This establishes a saner dependency structure for the recipes; skia_vars
is at the bottom level, skia_step depends on it, skia_flavor depends on
both of them, skia depends on all of the above, and the recipes
themselves may depend on any or all of them.
Next steps:
- Merge buildbot_spec into skia_vars
- Move test_steps and perf_steps from skia recipe_module into
swarm_test and swarm_perf recipes
- Cleaner checkout_steps process
